Hi Marcelo,
have you run across any tools besides namdenergy that this is a problem for?

In the case of namdenergy, I had not realized people would be wanting to
use it with AMBER parameters. I have never used AMBER parameters, so I
would appreciate it if you could send me a sample set of input files
(parameters, coordinates, namd input, and whatever else you need for the
run) to me so I can use the proper syntax and test it with NAMDEnergy. I
should then be able to send you a hacked version that will work for your
purposes, and add proper support to future versions of NAMDEnergy.
